7 VALVE FOR'GASOLENE AND OTH EB LIQUID FUELS.

To all whom it mag concern:

Be it known that I, FRANK CALDWELL, a a citizen of the United States, and a resident of Cincinnati, in' the county of Hamilton and State of Ohio, have invented'certain new and useful Improvements in Valves for Gas- 01 ne and other Liquid Fuels, of wh1ch the fo lowing is'a specification.

This invention relates to valve or controlling and comminglin devices for use invertical section of the valve in its preferred form; and Fig. 3, a plan view of the Valve or regulating-disk, showing the graduated,

circular series of openings or ports made therein.

In describing my device herein I will be gin byre'ferring to the apparatus of which ,80 my present-improvement 1s a part, in which,

1 indicates the intake-manifold, and 2 the exhaust-manifold, the ports of each being shown in dotted-circles.

The exhaust-manifold has a pipe 3 leadsfif'ing to the mufller, as customary, such pipe 3 being broken off and the mufiier omitted. 'The intake-manifold has a suitablefiange joint connection 4 with a coil or tortuouspassage 5, the latter, in turn, having a flangeoint connection 6 with a Y-bran'ch 7.-

, One branch of the Y-inember' 7 has screwthreaded connection with agas controlling chamber 8 and the other branch of said member 7 has screw-threaded connection with an air controllin chamber9.

The control in -chambers 8 and 9 are su plied with flexib e-conductors 10 and 11', respectivel the conductor 10 leading to the gas-supp y and the conductor 11 leading to a suitable air supply means.

It is in connection with thespecific structure of each of the gas and air controllingchambers- 8 and 9, respectively, that I have to deal with principally herein, as those p i'ng-button 34 that may have ,a. pointer 35, the latter being adapted to bemanipulated, p

features form the essential elements of the Specification of Letters Patent. Application m June 1a, 1016. Serial No. 104,0.

lingde'vices'bein practically alike, -I will proceed to descri e the one for controlling the air supply, which will answer for both.

The sa1d air-controlling device is composed of a shell made up of two cylindrical parts 17 and 18, the part 17 havin its outerend internally screw-threaded or attachment to an externally-threaded end of one of the branches 41 of the Y-member 7. The

jacent ends to provide for a coupling band or ring 19, the latter being internally-threaded and adapted to secure the said adjacent ends of the members 17 and 18 at the do sired distance or space apart, as best shown in Fig. 2. The said adjacent, ends of the members 17 and 18 are made correspond-c ingly sloping so as to rovide. the concaveend 20in the member 1 and the convex-end 21 in the member 18, the space between. saidends 20 and 21 forming a valve-chamber in- Which a disk 22 is placed, such disk taking the same slope, or being of the same conical form to suit the adjacent faces of said adjacent ends of the members 17 and 18 and with its upper or convex face in Contact with the lower concave-face of the end 20 of the said member 17 but' free to be duly rotated within the chamber between the said ends 20 and 21. The end 20 has a central-extension 23 and the member 18 has a centraltubular portion 24, for the accommodation of the valve-stem 25.. The inner end of the valve-stem 25' is secured in place by means of a cross-pin 26 to an extension 27 made 27 being shallower than and extending with- .inthe socket 28 made in the central-extension 23 7 i said bottom 20. A spiral spring 29 encircles the valve-stem 25 within a central bore 30 made in the upper end ofthe member 18 and its purpose is to keep the up or face of the disk 22 in frictional-contact with shall freely seat'and be duly held in adtime, be ada ted to be rotated thereunder. The outer-en of the valve-stem 25 extends beyond the outer-end 81 of the member 18 to at the center of the disk 22, such extension 1 justed position thereon and, at the same which outer-end 31 a plate 32 capable ofre- 33,'and said outerend of the valve stem is .made square to accommodate a knob or turnat two cylindrical portions 17 and 18 are shouldered. and externally-threaded at their ad the lower face of the bottom 20 so that it a customary to ha vcEthc gas-passages of lcs.

- apparatus of this character.

:air and gas are mixed and pass onwardly l as customary, in relation with the dial plate 32 to cooperate with a suitable dial carried thereby. i

A circular series of perforations 36, 3G, 36", 36, 36", 36, that are of radually'decreasing diameters down to t to one 2-57 of least diameter are made in the conical valvedisk 22, as best shown in Fig. 3, but also shown in Fig. 2, the latter view, however, showing but two of such perforations.

'38 indicates the air-inlet leading, into the chamber 18, and 39 indicates the port-hole in-the convex-end 521 of said chamber 18, such port-hole 39 being the exitulor the air intothe'valve-clnnnbcr where it. is under the control of the valve for passage through the desired one of the graduated port-holes in said valve into and through the orifice 40 made in the concave-bottom 20 of the air-chamber 17, whence it passes onwardly into the branch 41 of the Yoncn'iher Land thence ci'iconnters the hallic or partition 42thai is located in said Y-hranch from the crotch 43.tlicreoi' centrally across to the flange-joint. member (3. the hatllc leaturc being as best shown dotted in Fig. 1. The deseription of the air-controlling nn-mhi-r I) will answer as well for thatolf the ,Q'asa'nnstrolling member 5, hut, the latter is of sonic:

what lesser capacity or size in relation to said mcmberll for the reason that. it is capacity than those of the z'iir-passagcsin [he halllc or partition 42 is provided-in the throat of the Y-membcr 7 so as to receive the 'n'cssurc oi air. and gas on its opposite. sides and to do' liver them at the tlange-joint; (7, where the into the coil or tortuous spiral 5. where such admixture becomes further intermingled until'it reaches the flange-joint I, \\'ln'l|co it passes into the intakc-nianil'ohl 1 ready for dischargeinto the place oi combustion and use. i
